To all whom a't mag concern:

. Be it known that 1, Answer 0. Roman, a

citlzen of the United Stat es residing 'at Cleveland, in the county of duyahoga and State, of Ohio, have invented certain new and useful Improvements in Records for of which the fol- Phonographic Machines, lowing is a specification.

This invention pertains to records for phonographic machines, and the invention strip of flexible material of the.

consists m a nature of a ribbon or sound reproducing c annels or formed therein and substituted or the cylinders or disks heretofore commonly used for this purpose.

In the accompanying drawings, Figure 1 is a plan view of a repr' ducing mechanism and a record embodyir my invention, and Fig. 2 is a sectional elevation of said mecha nism, lengthwise and showing 'a record mounted on a pair of rolls and a bearing roll between the same over or upon which the reproducing needle operates. Fig. 3 is a plan view corresponding substantially to Fig. 1 except that the reproducing mechanism is omitted and the middle portion of the rec- 0rd strip is broken out, bringing the two ends near together and showing the sound lines or channels enlarged.

The invention is comprised, first, in the sound recording strip 2. This strip is dis tinguished from all the prior art lmown to me by its flexibility and adaptability to be rolled or wound upon drums, rolls or spools 3 and to which the ends of the strip or film can remoyably secured. For example, in i, the said receiver is presumably on its way, by line, across the surface of the record and will end with the lastline on the finishing side of the strip. But if the iece of tape having operation be as shown in Figs. 2 and 3, with the strip wound initially on one roll 3 when the operation begins and adapted gradually to wind on the other roll as the reproduction proceeds, the shift from one sound line to the other may be made from-line to line. Or if each line represents the receiver may stop at the end of any one of said lines or be shifted to the next in a continuous movement in any way provided for the purpose.

The sound receiver or instrument 4 is fashioned substantially after the usual receiver with a diaphragm and the like, an

" .1. 7 thereon runs in the sound 1:01.

OOVGS parallel record grooves an entire piece 1 nels and transmits the sound to the receiver, as usual 7 The tubulartpivoted arm 8 connec ts w1th the side 0 the receiver and serves both as a support therefor and as a.

sound transmitting medium to the horn usually connected with said tube but not shown herem.

' The bearingroller 6 for the strip 2 between the two end rolls is adapted to su portthe said strip directly beneath th needle 7 and to cocperate therewith. A medium hard rubber sleeve 9 or the like.

covers the said roller and usually the roller} rotates responsively to the travel of the strip 2. p

The terminals or ends of strip 2 which fasten to spools 3 are shown in Fig. 3, andthe linear sound record thereon as represented by the wavy lines 5 begins at theright at A and extends by a switch back into the second arallel line from the topv at the left at B. hen this second line switches back at the right at G into the third line from the top, and the succeeding lines are similarly joined to produce a series of independent sound records arranged in parallel lines but so joined that only a reversal of travel of the strip is required at stated intervals to shift the sound reproducing needle from one to another successively. The junction of the is preferably arranged as shown in Fig. 3, after the manner of a switch back railway, the inclined portions 10 of the room serving to shift the sound box and sty us into line with the return groove, which will then be readily followed by the stylus, as its inclination is reversed. The strip may be of any given length so that each line may represent a complete record, or two or more successive lines may be used to comprise a complete record divided into sections representing separate verses or chapters of a musical or dramatic composition, etc. In this way a relatively narrow band or strip may embody innumerable selections, or a single composition of great length and duration, and by the use of motor driven mechanism adapted to automatically reverse the movement of the strip when the needle is switched from one line to the next, it is possible to give a continuous performance for an indefinite period of time which is only limited by the width and length of the strip and the number of lines thereon.
